Kodi pali kusiyana kotani pakati pa methyl cellulose ndi cellulose?

Methyl cellulose ndi cellulose ndi ma polyscharides, kutanthauza kuti ndi mamolekyulu akulu opangidwa ndi mafani obwereza a mamolekyulu osavuta. Ngakhale anali mayina ndi mawonekedwe omwewa, zinthuzi zimakhala ndi kusiyana kwakukulu malinga ndi kapangidwe ka mankhwala, katundu, ndi mapulogalamu.

1. Kapangidwe ka mankhwala:

Cellulose:
Cellulose ndi polymer mwachilengedwe chifukwa cha mayunitsi a glucose omwe amalumikizidwa pamodzi ndi β-1,4 glycosiidic. Mayunitsi a shuga awa amakonzedwa mu maunyolo a mzere wautali, ndikupanga zida zolimba, zosakhwima. Cellulose ndi gawo lalikulu la makhoma a cell a mbewu ndi algae, ndikuthandizira mwadongosolo komanso kuunikiridwa.

Methyl cellulose:
Methyl cellulose ndi zochokera ku cellulose zomwe zimapezeka pochiza cellulose ndi njira yolimba ya alkaline yolimba ndi methyl chloride. Mankhwalawa amabweretsa zolowa m'malo a hydroxyl (--Oh) ma molecule Molelule ndi methyl (-ch3). Mulingo wa zolowa m'malo (DS) amatanthauza kuchuluka kwa ma hydroxyl omwe adalowa mu gawo la glucose mu cellulose mu cellulose unyolo ndikuwonetsa zomwe zimachitika cellouse. Nthawi zambiri, ds wapamwamba amatsogolera ku kuchulukitsa kusungunuka ndikuchepa kutentha kwa kutentha.

2. Katundu:

Cellulose:
Insuluble m'madzi ndi okhazikika ambiri chifukwa cha kulumikizana kwake kwapakatikati hydrogen.
Mphamvu yayikulu komanso kuuma, imathandizira pantchito yawo yothandizira kuthandizira mbewu.
Biodeggramble komanso yokonzedwanso, ndikupanga chilengedwe.
Kukula kochepa kochepa m'madzi.
Nthawi zambiri, cellose sioyenera kumwa mwachindunji ndi anthu chifukwa chochititsa chidwi.

Methyl cellulose:
Sungunuka m'madzi kuti musungunuke madigiri otengera kuchuluka kwa mpweya.
Mawonekedwe owonekera ndi ma viscous pomwe amatha kusungunuka m'madzi, ndikupangitsa kuti ikhale yothandiza pamapulogalamu osiyanasiyana monga omata monga azosalonda, zokutira, ndi othandizira kukula kwa zakudya.
Kutha kupanga ma gels kumatenthedwe okwezeka, omwe amapezera njira yozizira. Katunduyu amapeza mapulogalamu ogwiritsira ntchito mankhwalawa, komwe amagwiritsidwa ntchito ngati matrix a gel omwe amasulidwa.
Osati poizoni ndipo nthawi zambiri amadziwika kuti amagwiritsidwa ntchito ngati chakudya chowonjezera, emulsifier, kapena wokula.

3. Ntchito:

Cellulose:
Gawo lalikulu la mapepala ndi makatoni chifukwa cha mphamvu ndi kukhazikika kwake.
Kugwiritsidwa ntchito m'matumba ndi nsalu, monga thonje komanso nsalu, chifukwa cha zotupa zake zachilengedwe.
Zowonjezera zopangira cellulose zochokera ku cellulose monga methyl cellulose, carboxymethyl cellulose (cmc), ndi cellulose.
Wopezeka m'zinthu zowonjezera mazira, ndikupatsa zochuluka kuti agwetse chimbudzi.

Methyl cellulose:
Kugwiritsa ntchito bwino makampani ogulitsa zakudya monga kukula kwamphamvu, kukhazikika, ndi emulsiferier mu zinthu ngati msuzi, sopo, ndi zakudya.
Mapulogalamu ogwiritsa ntchito mankhwalawa amaphatikizanso kugwiritsa ntchito ngati chophimba mu piritsi, wothina bwino kwambiri ndi mafuta onunkhira, komanso mafuta omwe amapezeka pakamwa pochotsa mankhwala osokoneza bongo.
Amagwiritsidwa ntchito popanga zomanga monga matope ndi pulasitala kuti apititse patsogolo kutopa komanso kutsatira.
Olemba ntchito pazinthu zachinyengo ngati shampoos ndi zotupa chifukwa cha kukula kwake komanso kulimbitsa katundu.

4. Zotsatira za chilengedwe:

Cellulose:
Cellulose isinthanso komanso biodegramble, ndikupangitsa kuti zikhale ochezeka.
Ndi gwero losakhazikika monga momwe lingathere kuchokera ku zinthu zingapo zopangidwa ndi mbewu, kuphatikizapo zamkati, thonje, ndi zotsalira zaulimi.
Zipangizo zochokera ku cellulose zimatha kubwezeretsedwanso kapena kuphatikizidwa, kuchepetsa chipululu ndi chilengedwe.

Methyl cellulose:
Methyl cellulose imachokera ku celluluse, ndikupangitsa kuti akhale mofatsa komanso ochezeka.
Komabe, kusinthasintha kwamankhwala kumafunikira kupanga methyl cellulose kumaphatikizapo kugwiritsa ntchito mankhwala monga alkalis ndi methyl chloride, yomwe imatha kuwonongedwa zachilengedwe ngati sizikukwaniritsidwa bwino.
Njira zotayidwa ndi njira zoyenera kuchitira chithandizo ndizofunikira kuchepetsa kusintha kulikonse kwachilengedwe ndi kupanga ndi kugwiritsa ntchito methyl cellulose.

5. Kumaliza:
Methyl cellulose ndi cellulose ndi mankhwala okhudzana ndi kusiyana pakati pamapangidwe awo, katundu, ndi ntchito. Celloulose imakhala ngati chinthu chopangidwa muzomera ndikupeza ntchito zopanga mafakitale ndi mapepala, ndi ofunika kwambiri pa mafaloni osiyanasiyana kuphatikiza chakudya, ndi zomangamanga. Zinthu zonse ziwirizi zimapereka zopindulitsa zapadera ndikuthandizira kuti pakhale zinthu zingapo, zomwe zimagwiritsidwa ntchito ndi cellulose kukhala chilengedwe komanso kuchuluka kwachilengedwe ndi methyl cellulose yowonjezera magwiridwe antchito komanso magwiridwe antchito ena. Kuzindikira kusiyana pakati pa methyl cellulose ndi cellulose ndikofunikira pogwiritsa ntchito mankhwalawa moyenera komanso modekha pakuchepetsa mphamvu.
